Geometry of Scattering at Planckian Energies

We present an alternative derivation and geometrical formulation of Verlinde topological field theory, which may describe scattering at center of mass energies comparable or larger than the Planck energy. A consistent trunckation of 3+1 dimensional Einstein action is performed using the standard geometrical objects, like tetrads and spin connections. The resulting topological invariant is given in terms of differential forms.Comment: 8

Performance of the ATLAS Tau and Missing Energy triggers with 7 TeV proton proton collisions at the LHC

A study of the performance of the ATLAS tau and missing energy triggers with data collected in spring 2010 at {\surd}s = 7 TeV proton-proton collisions at the Large Hadron Collider (LHC) is presented. A comparison was performed between data and Monte Carlo simulations for the tau and missing transverse energy triggers. As well as a comparison between missing transverse energy trigger quantities and their offline reconstructed counterparts. Tau trigger results compare well with predictions from Monte Carlo simulations. Slight deviations are observed for tau shower shape quantities. Possible sources contributing to the discrepancy such as the simulation of the underlying event are currently being studied. The missing transverse energy reconstructed by the Event Filter is well correlated with the offline result. In addition, there is good agreement between the results obtained with collision data and Monte Carlo simulations.Comment: 3 pages, Proceedings for the Hadron Collider Physics Symposium 201

Marginally stable solutions

In previous work constant magnetic field strength solutions for SU(2) gauge theory on a torus were found, which somewhat surprisingly turned out to be classically stable. This was called marginal stability, as moving along one of its zero-modes, two of the stable modes turn unstable. Here we investigate the stability under quantum fluctuations in the domain where the solutions possess the marginal stability at the classical level.Comment: 4p with 2 figs, as one uuencoded PostScript.gz file, presented at Lattice'95, Melbourne, 11-15 July, 199

Identities, Conflicting Behavioural Norms and the Importance of Job Attributes

The paper empirically expounds the richness of the identity approach to labor market behavior by allowing individuals to experience identity conflict. Specifically, it investigates the relationship between the importance individuals attach to labor-market activities – which is influenced by the identity to which they adhere – and their preferences for job attributes. The analysis shows that individuals who consider labor-market success as instrumental for achieving their life goals tend to attach importance to job characteristics such as pay level and career and training opportunities. Individuals for whom non-labor market activities are important and in conflict with labor market activities are found to attach importance to the possibility of working on a convenient time schedule. Moreover, consistently with the identity approach to labor-market behavior, men appear to resolve the conflict between career and non-work activities in favor of the former. Finally, unobserved factors that increase the desire to work part-time have a negative impact on the likelihood of attaching importance to training and career opportunities offered by the job.job attributes, social identity, role conflict, part-time

Updates in metabolomics tools and resources: 2014-2015

Data processing and interpretation represent the most challenging and time-consuming steps in high-throughput metabolomic experiments, regardless of the analytical platforms (MS or NMR spectroscopy based) used for data acquisition. Improved machinery in metabolomics generates increasingly complex datasets that create the need for more and better processing and analysis software and in silico approaches to understand the resulting data. However, a comprehensive source of information describing the utility of the most recently developed and released metabolomics resources—in the form of tools, software, and databases—is currently lacking. Thus, here we provide an overview of freely-available, and open-source, tools, algorithms, and frameworks to make both upcoming and established metabolomics researchers aware of the recent developments in an attempt to advance and facilitate data processing workflows in their metabolomics research. The major topics include tools and researches for data processing, data annotation, and data visualization in MS and NMR-based metabolomics. Most in this review described tools are dedicated to untargeted metabolomics workflows; however, some more specialist tools are described as well. All tools and resources described including their analytical and computational platform dependencies are summarized in an overview Table

New Instanton Solutions at Finite Temperature

We discuss the newly found exact instanton solutions at finite temperature with a non-trivial Polyakov loop at infinity. They can be described in terms of monopole constituents and we discuss in this context an old result due to Taubes how to make out of monopoles non-trivial topological charge configurations, with possible applications to abelian projection.Comment: 6 pages, 2 figures (in 5 parts), latex using espcrc1.sty, presented at "QCD at Finite Baryon Density", April 27-30, 1998, Bielefeld, German

The QCD vacuum

We review issues involved in understanding the vacuum, long-distance and low-energy structure of non-Abelian gauge theories and QCD. The emphasis will be on the role played by instantons.Comment: 12p with 7 figs. Review presented at Lattice'97, Edinburgh, 22-26 July, 199

Cosmopolitanism, identity and recognition

An application of the social theory of Axel Honneth to global justice, arguing that development goals must include provision for the intersubjective recognition required for identity formation. In the disciplines of Political Philosophy and International Relations cosmopolitanism is often defined as the view that all people, no matter their national, ethnic or religious backgrounds and no matter what their gender, have an equal moral status. The most telling enunciation of this view is the United Nations&rsquo; Universal Declaration of Human Rights. However, the focus that is given to rights and a global form of legal equality by this document and by such theorists as John Rawls is not rich enough to capture all of the ethical demands that global society places upon well-to-do Westerners and developed nations. This paper makes use of a thesis by Axel Honneth to the effect that political thinking needs &ldquo;a basic conceptual shift to the normative premises of a theory of recognition that locates the core of all experiences of injustice in the withdrawal of social recognition, in the phenomena of humiliation and disrespect.&rdquo; Honneth identifies three spheres of recognition in modern societies: love, law, and achievement. I offer some exposition of his theory and then argue that global justice must be understood to embrace the substantive ethical values that arise in these three spheres as well as the procedural standards of moral rightness that belongs to the second of them. Such an expanded conception of global justice will yield an enriched conception of cosmopolitanism.<br /
